Specification of Letters Patent.

Application filed March 5, 1918. Serial No. 220,630.

To all whom it may concern:

Be it known that 1, MICHAEL Semen- BAUER, a citizen of the United States got America, residing at Warren, in the county of Macomb and State of Michigan, have in- :vented certain new and useful Improvements in Vehicle-Wheels, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to vehicle wheels, and has special reference to that ty e of wheel used in connection with automo trucks and similar vehicles, and generally to provide novel means in eguipped with a pneumatic or solid rubber tire. v

.The primary object of my invention is a manner as hereinafter set forth for converting a light duty wheel of the above type into a heavy duty wheel, as far as the tra'ctionot the wheel is concerned, so that a narrow tread wheel can be used on soft or irregular will cooperate reference will now ranged to permit of the tread attachment being easily and quickly placed in position, without any danger of the attachment becoming accidentally displaced in the operation of the wheel.

The above and other objects are attained by. a mechanical construction that will be hereinafter described and then claimed, and be had to the drawing, wherein- Figure 1 is a side elevation of the wheel; Fig. 2 is a tread elevation of the same;

Fig. 3 is an enlarged cross sectlonal view taken on the line lH-IIT of Fig.

Fig '3 a similar view illustrating a modificatio..- or my invention, and

Fig. 5 is a perspective view of a portion of the tread member, showing a spur retain- 7 ing device.

A wheel in accordance with my invention comprises a hub 1, spokes 2, a folly 3, and a band 4 on said felly.

iles,

. which may be distributed on On the band 4 is mounted a rim5, which Patented sea; a, 19 m,

may be secured thereon by bolts 6 and nuts d 7 the bolts 6 extending through the band 4 and the telly 3 with the heads of said bolts countersunk in the rim 5 and the nuts 7 on the inner ends of said bolts. The rim 5 has side flanges 8 adapted for holding a pneumatic or solid rubber tire 9, and said rim is of greater width than an ordinary rim,-s0 as to protrude from the sides of the folly 3 andthus provide side rings 10.

On the solid rubber tire 9 is placed an annular tread member 11 of considerable width, said member being in the form of a strip of metal bent about the tire with its ends inturned so as to provide lugs (or flanges 12, as best shown in Fig. 1, adapted to be connected by bolts 13 and nuts 14. Encircling the bolts 13, between the lugs 12 are coiled expansion springs 15, and the expensive force of these springs maintains the ends of said member 11 normally separated,

but permits of the ends or lugs 12 approaching each other when pressure is brought to bear upon the tread member 11. I

To close the gap between the lugs 12 of the tread member 11, a plate 16 is mounted on one end of the tread member to extend over the gap on to the opposite end of the tread member, thus preventing stones and other matter from lodging between the lugs 12 and interfering withadjustment thereof.

The tread member 11 is connected to the side rings 10 by a plurality of radially disposed and equally spaced bolts 17 arranged at both sides of the tire 9. The bolts 17 extend through slots 18 in the tread member 11 and have the headed ends thereoi connected by cleats 19 on the tread member 11. The inner ends of the'bolts are provided with nuts 20 and encircling said bolts between the side rings 10 and tread member 11, are coiled expansion springs 21. r

, wheel.

The tread member' '11 may be provided with a plurality of detachable spurs 22 the periphery through the tread member 11 and wall of the tread member 11. Theresilient' arms or springs 25 can be easily sprung out of engagement with the spur shanks 24 when .it is desh'ed to remove said spurs.

In or er that the tread member may be 4 used on ordinary wheels that are devoid of the wid -rim or side rings, there is shown in Fig. side rings 27 that are bolted or otherwi e connected, as at 28, to a felly 29. In this instance itvis necessary to use longer side bolts 30 and longer springs 31, but the same results are attained as in the preferred form of construct-ion.v

It is thought that the utility of my inven-' tion will be apparent without further description, and while in the drawings there are illustrated the preferred embodiments of the wheel, it is to be understood that the structural elements are susceptible tolsuch variations and modifications as fall witlgimthe scope of the appended claim.

What I claim is In a wheel, the combination of a resilient tire, a rim supporting said tire, side rings integral with said rim adjacent the tire, a tread member on said tire in the form of a stri of metal having its ends inturned, bolts an nuts connecting the inturned ends of said tread member, springs on said bolts holding the ends of said tread member normally separated so that said tread member may be contracted about the tire of said wheel, a plate on' one end of said tread mem-' ber extending on to the opposite end of said tread member and bridging the gap between the inturned connected ends of the tread member, bolts connecting said tread member to said side rings with said bolts loose in said tread member, and coiled expansion springs on said bolts between said side rings and said tread ,member.---

In testimony whereof I ailix my signature in the presence of a witness.
